Specification of Letters Patent. Patented April 20, 1909.

Application flled' January a, 1960. Tsar-1'51 No. 474 ,2s1.

Be it known that I; HUBBARD JosLn N Y citizen of the United Statesjand resident Syracuse, inthe county-of Onondaga and State of New York, have invented certain.

; new and useful Improvements --in Type- Writing Machines, of which the'following is a specification.

- 1 My inventlon relates to retarding contriv- 1 0 its main object to provide improved devices anc'es for typewriting machines and has for of the class specified. I

. To the, above and other ends the invention consists-in the features of-construction,- comblnations of devices and arrangements of parts hereinafter described and partlcularly pointed out in the claims.

My invention is illustrated as applied to a Monarchtypewriting machine but may adapted to other styles of writing machlnes.

. Said invention'is designed as an improvement on the construction disclosed n the pending application ofJac'ob Felbel Serial No. 473,440, filed January 21st, 1909.

"In; the drawingslFi'gure-l is .a vertical longitudinal sectional view of .a Monarchv t'pewriting machine-embodying my inventi on parts of the inachine being omitted and parts broken away.

Fig. 16' is a front view of t e m'odi fied contrlvance shown in-Fifi. 15. Fig. 17' is a"per'spective view of 't e supporting Referring first to Figs. 1 and 2, the'base" 1 has rising from it corner posts .2 which" support a top plate 3, these parts constitut-l ing the main frame of the machine. .Type bars and their actuating devices (not shown) are mounted on the main frame, said type: bars cooperating with a laten 4 mounted on a carriage oomposedo end bars' 5 and a slideb'ar 6. The slide bar is grooved at its top and bottom faces to. cooperate with bearing balls 7 which also cooperate with ooved guiderails 8 secured to curved stan ards 9.

Arms 10 pivoted on the end bars of the carriage carry a spring-pressed .feed rack 11 which normally meshes with a feed pinion 12 fixed to the front end of a horizontal 'shaft l3 journaledon a bracket 14f An escaper'nent wheel'1 5 is operatively connected with the shaft and cooperates with feed dogs 16Jand-17 supported on adog rocker 18 pivoted at 19 on a bracket 20; A link21 connects theidog rocker witha universal bar (not shown) which isoperatedby the key levers. spring drum 22 contains the usual main sprm and is connected-by a' strap 23 with a pm 24 depending'from the carriage. The main spring tends constantly to draw the carriage leftward over the top plate, the carriage movements in this direction', however, bein usually controlled by the operation of the escapement devices during the printing orspacing of the differentcharacters as the lines are written,

'The drawings illustrate a tabulator mechan; isin like that disclosed in the patent to Fe}- be'l No. 904,689, granted November24, 1908. 5

,Wardly extending ends of, a series of levers 27 pivoted at 28 on a- -frame 29 detachably secured to the mainframe of the machine.

"A toothed stop bar 25 mounted at the rear Coiled springs 30 cooperate with the lower I forward end of one of the slide bars liach rock shaft has fixed to it also a tabulator lever 35 provided with a lrey'33.

When any tabulator key 36 is operated it turns its rock shaft 33, causing the arm-34 fixed thereto to push the associate slide bar 31 rearward, said slide bar actuating one o the denomination levers 27 to bring the stop portion. at the upper end of said lever into the path of the column stops 26. A universal bail 3'4" operative by the levers 27 to actuate the carriage releasing mechanism is pivoted at 38 on the frame 29. The bail has an extension 39 which is pivotally connected with the lower end of an upwardly extend ing lint: which is pivotally connected at its upper end to one arm of a lever d1 fulcrumed at lz in a bracket 43. The same arm or" the lever d1 pivotally supports at 44; a lifting device which bifurcated at its upper end to embrace loosely the shaft 13 through cut-outs iu the bracket 14. In. the patented construction the bifurcated upper end portions of the lifting device 15 are rovided with lifting shoes, but these liftmg shoes are dispensed with in the present case and the lifting device is formed in stead with a lateral extension 4:5 which has a horizontal slot 45, which slot connects the lifting device with the retarder contrivance so that the release of the carriage may be ctlected by the same operation which cbnnects thoretarder contrivance with said carriage.

The rctarder contrivance devised by' me in the present case is an improvement on the intermittent retarder contrivance disclosed in the pending application of Jacob Felbel 'hereinbefore referred to.

The. contrivance as a whole is pivotally supported on a bracket- Wliich as best shown in Figs, 3, t and 5 is composed or: two right angled plates 16 and 4-7. The plate l? has a horizontal arm which rests on a cori'esponding horizontal arm of the plate 46, the two plates being suitably secured together as by brazing and being fixed to the topv plate 3 by a headed screw 48 which passes through a hole in the bottom plate to. The upstand- 'ing arms of the plates 46 and 17 are'spaced apart to receive between them theretarder contrivance which is pivotally mounted on a headed and shouldered screw l9. Said screw as appears n F 1g. 5, engages holes in said upstanding arms, the opening in the plate 4? being threaded to receive the reduced and threaded end portion of the screw ll). The casing which contains the retarder devices consists of a box-like part 50 and a cover plate 51 therefor. As will be understood from an examination of Figs. 3, -1- and 5, thebox 50 is composed of two circular connecting chambers, one somewhat larger than the other. The cover plate 51 is of corresponding shape in plan as shown in Fig. 8, and is formed with notches 51 which are adapted to receive corresponding lugs 50 projectin from the edge of the box 50 giving a sort of dove-tail construction such that when the box and its cover are secured together by the screw 49 the cover is prevented from accidentally sidewise.

Before the casing is assembled and mounted in place on its supporting bracket, various devices comprised in the retarding mechanism are arranged in the box-like part 50 and their construction and arrange ment will be clearly understood by reference to Figs. d to 8 inclusive in connection with the following description. A gear wheel 52 arranged in the larger circular chamber forming part of the box 50, said gear wheel. being adapted to contact with a thin boss 51 formed on the inner face ofthe cover plate 51, this construction being provided to prevent the entire face of the gear Wheel 52 'gear Wheel to rotate on said screw. A rotary checking device or cam carrier in the form of a sleeve 57 is formed with a central hearing opening 58 through which the pivot screw l!) passes, the sleeve being confined between the hub 54; and a thin boss 50" thereof.

The sleeve 57 carries on its periphery two oppositely disposed checkingdevices or cams 59 and 60, the outer face of each cam gradually curving away from the center of rotation of the sleeve. A pin. (31 on the sleeve 5? enters the cut-out in'the hub 54:

slipping off' formed inside the box 50 on the bottom face and being adapted lo-operatively engage 'Winding up the spring 62 until the shoulder 55*. is brought into contact with the pin 61,

after which the sleeve 57 will be forced to turn with the ear 52. Codperativ'e with the cams 59 an '60 is a checking device in the form of a circular leaf spring 63 which is arranged within the larger circular end of the box 50. One end of the spring 63' is suitably secured as by rivets 6a to theinner wall of the box and the opposite end is bent or-dou-bled back on itselfand then curved inward to provide-"a contact portion or tongue 63 with which the cams 59 and 60 may be caused to coiiperate. A screw 65 passes through and is supported on thebox 50, the inner end of the screw 65 contacting with the circular part of the spring 63 some distance from its free end. Byscrewing in the screw 65 and setting it by the nut 66 the pressure or checking effect exerted by the spring tongue-'63 on the cams 59 and 60 ma be increased. Conversely the checking ect may be lessened by unscrewing the ".SCIGW 65, permitting the circular portion of the spring 63 .to approach closer to the inner wall of. the box 50. The operation of the checking devices 63*, 59 and 60 will be explained more fully .later on; The gear wheel 52 is adapted. to be connected with the carriage toreceive motion therefrom when the latter is-relcased, by a train of devices which includes a' smaller gear wheel 67 having a hub 68 and-being fixedto a. shaft 69 by a pin 70 passing transversely through said hub and shaft.

The gear 67 and its hub are confined between "athin boss 51 on the inner face of the cover plate 51 and a thicker boss integral with the box 50. The gear 67 and the shaft 69 are thus held from endwise motion but may turn freely when actuated." The shaft 69 projects forward outside a hearing boss 51 on the cover plate 51 1 and carries a toothed wheel orpinion 71 having a hub 72 by which said pinion is suitably secured to 50 theshaft 69." The pinion 71 underlies the feed rack 11 and isnormally maintained separated therefrom by devices which include 'a wire restoring spring 7 3 one end of by a screw-F74: to the bracket arm 47, the free end pf the spring engaging the boss 51.

In assembling the'parts,.the bracketlis secured to the top plate by thescrew 46", the hub-72 being first arranged in the slot 45" 160' in the lifting device 45. .-When a tabulator key 36 is depressed, the associate stop lever 27 will be. projected-into the path of the columnstops 26 and, at the same time the universal bar 37 will be moved rearward, ramrng the link i6 and causlng the liftingdevice to be raised, thereby swinging the retarding contrivan'ce on its pivot 49 and bringing the pinion 71-into engagement with the feed rack 11, thus connecting the retarding contrivance with the carriage. Thereafter the upward movement of the pinion 71 is continued the feed rack 11 will be dis-1 engaged from the feed pinion 12, thus freelog the carriage and pernnttlng -1tto be drawn leftward until arrestcdby the tabu'' As thecarriage starts to run lator stops. I leftward its motion will be transmitted bythe pinion 71 and gear 67 to the gear'52 and its hub 54. The hub 54 inturn causes rotation of the sleeve 57 and the cams thereon. It may beassulned that at the start the parts will be in the relations shown in Figs. 4 and lO'which are views from opposite sides, Fig.

10 illustrating the arts as, viewed from the front. The spr1ng'63 is considerably stronger than thespring 62 so that with the cam 59 in engagement with the spring tongue 63 the sleeve 57 will be momentarily held from turning although the spring 62 be urging it ahead. The rotary movement of the wheel 52 will cam the shoulder 55 to separate from the ,pin 61 and wind up the spring 62- until the shoulder 55 contacts with the, pin 61, asshow-n in Fig. 11. Up

to this time the leftward movement of the carriage has been substantially free and unobstructed and said carriage has consequently acquired considerable momentum; tent of the free movement, of course, de-

pends on the proportioning and arran ements of the parts as well as on the position of rest from which the retarding devices start. i

Afterthe shoulder 55" contacts with the pin 61 asshown in Fig. 11 the sleeve 57 will The oxbe forced to turn and the cam 59 will be forced past the spring check 63. The parts will" then be in the relationships showniin Fig.

12. As soon as the cam 59 is free from the spring tongue 63, thes prin'g 62 will operate to turn the sleeve 57 forward or in the: directionof the arrowin FigL-12 until said sleeve is arrested by the engagement of the cam 60 with the. spring ton ue 63 as shown in Fig.

13. As the sleeve urns, the gear wheel and its hub 54LW1llloe' advanced to some extend because of their connectlon with the cai'riagewln'ch is also advancing; but no attempt ha's'been made to' show the extentof said advance in Fig. .13. When the independent advance of the sleeve 57 has, been "ended by the engagement of-Qthe cam 60' with the spring end 63f-,-. said sleeve will re-. main substantially -qulescent until the ad-' vanc e of the gear wheel I 52 brings the vshoulder 55 into 'contactwith -the ;pin 61 on 'said sleve- Thereafter the sleeve 57 will be forced ahead by the hub 54,-untilthe can'160 has been forced-past the sprin and has reached the dotted h s position tongue 63" the retarder contrivance.

shown in Fig. 14. The spring 63, of course, yields to permit the cam 60 to be forced past. As soon as the cam 60 is clear of the spring tongue 63, the sleeve 57 will be advanced independently by the spring 62 until arrested by the engagement of the cam 59 with the springtongue 63 as shown by full lines in Fig. M. The sleeve will then remain quiescent until it is again forced ahead by the engagement of the shoulder with the pin 61, provided the movement of the carriage prior to its arrest by the tabulator stops continues far enough to permit of such engagement and forcing ahead.

When the carriage is finally arrested one or the other of the cams 59 and 60 will be engaged with the spring end 63*. If, when the arrest takes place, the spring 62 has been wound up to any extent by the independent advance of the sleeve 57, said spring 62 will unwind when the tabulator key is released and the retarder contrivance is disconnected or separated from the carriage. The end of said spring which is connected with the sleeve 57 will at this time be fixed by reason of'the engagement of one of the'cams with the spring end 63. 'Consequently the spring 62 will unwind from its other end, turning the hub 5%, gear 52, gear 67 and pinion 71,

in reverse direction until the abnormal tension in the spring 62 is entirely taken out and the spring is in its normal condition, at which time the shoulder 55 will be in contact with the pin 61. It will be seen that the sprin' 62 is a double acting one and that at one time it operates to move or turn the device with which it is connected at one end while at another time said spring will operate to move or turn the device with which it is connected at its opposite end.

Various changes may be made withinthe,

scope of my present invention. Examples of such changes are shown in the modified construction illustrated in Figs. 15 to ll. It was found desirable to raise the pivotal center about which the retarder c'ontrivance turns in order to facilitate the connection with and disconnection from the carriage of Other changes to bring about this improved result consist first in the replacing of the restoring spring 73 by a coiled wire restoring-spring 73, the endsof which are secured one to a pin on the-retarglfer and the other to a pin on the supporting bracket; and second, in the re placing of the toothed wheelor pinion 7'1 by a pinion Tl, the teeth whereof are shallower or less dceply cut than those of the pinion Tl. The alterations necessitated by raising the pivotal center of the retardercontrivance include the replacing of the screw 49 by a headed screw 49, the latter screw being the shorter and terminating in a reduced and threaded end which extends outside the cover plate 51 and receives a nut 49". The

nut when tightened secures the cover plate to the body of the casing andmamtains the screw 49 in a fixed relationship with the casing. The supporting bracket of the first form is replaced by a supportin bracket somewhat differently shaped as ilustrated clearly in Fig. 17. The modified supporting bracket comprises two angled-plates 46* an 47 which may be suitably secured together as by soldering or by pins 7 5 or by both; or,

if. preferred, the bracket may be formed of a single piece of sheet metal punched and bent to the proper shape. portion of the plate 47 rests on the corresponding portion 'Of the plate 46, and the vertically disposed arms 46? and 47 are spaced apait to receive between them the retarder contrivance, as in .the first construction. But in the modified form the upright arms 46 and 47 'are curved or recessed as indicated at 46 and 47 to receive respectively the nut 49 and the head ofthe- At their upper ends saidarms are formed with hearing openings 4:6 and 47 which receive shouldered screws '76. The shouldered portions of these screws turn in said bearing openings while the re- The horizontal duced and threaded ends of the screws engage tapped openings in the casing. The construction is such that the screws 76 are screwed in fixed relationship with the casing and provide bearings therefor which are somewhat like trunnions. When the retarder contrivance is raised and lowered to bring the pinion 71 into engagement with the feed rack 11 and to disengage said pinion from said feed rack, the parts, owing tothe raising of the center of movement, are adapted to engage and disengage more readily than in the prior construction, the disenga ement being facilitated by the shallowness of the teeth of the pinion 71 and also by the coiled spring73, the power of which 'is employed more advantageously than was the power of the corresponding spring in the prior construction.

. Various changes besides-those described may be made without departing from my invention.

What I claim as new and desire to secure by Letters Patent, is 2- 1. A rctarder cont-rivance for typewriting machines comprising a rotary sleeve, a cam thereon, the outer face whereof is bounded by a curved surface the distance of which from the center of rotation of the sleeve gradually increases from one end of the cam to the other, and achccking spring engageable by the curved outer face of said cam.
